UPDATE:  One Interesting Take On Trump's Options From An Outside Perspective https://www.rumormillnews.com/cgi-bin/forum.cgi?read=160302

SCOTUS Rejects Texas Election Lawsuit Based On Standing, Not Mertis of Case. Three Trump Appointees Did Not Record Dissent. Two Justices Dissented.

Here is the decision
https://www.happeningdaily.com/supreme-letdown-high-court-rejects-lawsuit/

This case was cited by Alito in his dissent -       
https://en.wikipedia.org/wiki/Arizona_v._California

Here is one take on how that case sheds light on the Texas case - It is not usual for Supreme Court to take cases ORIGINATING with them. They usually take cases on appeal.   However the case above was cited because once in awhile they DO take "originating" cases, hence the Alito and Thomas dissent.  Next is to take more cases to lower courts and keep appealing up if necessary. GA Supreme filing was done by Giuliani after SCOTUS decision.

RUMOR:   SCOTUS Argued Over This  https://halturnerradioshow.com/index.php/en/news-page/news-nation/loud-arguments-in-us-supreme-court-chambers-over-texas-lawsuit-court-intimidated

Giuliani Spoke Directly After Decision

Open Cases as of Friday Night:

In Pennsylvania Rudy has a case he plans to take to the US Supreme Court. The couple congressmen from Pennsylvania still have a case at the US Supreme Court where they argue that the manner in which absentee ballots were processed in the state was unconstitutional.

In Michigan an Obama judge threw out Sidney Powell's case claiming massive corruption in the election process in the state. The judge must think carting tens of thousands of ballots into a counting area with no Republicans present is entirely fine. Powell has suggested she will forward this to the US Supreme Court.

In Georgia Lin Wood has a case now at the Supreme Court. Sidney Powell has a case which was thrown out which she plans to bring to the Supreme Court. President Trump has filed an emergency petition with the Supreme Court in Georgia.

A Tweet -

Sidney Powell
Pay attention! We made emergency filings in Supreme Court tonight for Georgia & Michigan. Will be filing Arizona Wisconsin shortly. These cases raise constitutional issues and prove massive fraud.
Our plaintiffs have standing
We The People will not allow rigged elections

Interesting Reactions From Texas, Including Secession Floated https://therightscoop.com/secede-texas-gop-chair-allen-west-issues-blistering-response-to-scotus-rejecting-election-suit/

From Epoch Times, this is the full list of who took this lawsuit seriously - just about everyone but the SCOTUS it seems     https://www.theepochtimes.com/supreme-court-rejects-texas-election-lawsuit_3615058.html

         "Nineteen Republican state attorneys general backed Texas in the lawsuit. The states they represent are Missouri, Alabama, Arkansas, Florida, Indiana, Kansas, Louisiana, Mississippi, Montana, Nebraska, North Dakota, Oklahoma, South Carolina, South Dakota, Tennessee, Utah, West Virginia, Arizona, and Alaska. Six of the states filed a motion to join the case as intervening parties: Missouri, Arkansas, Louisiana, Mississippi, South Carolina, and Utah.

Meanwhile, 20 Democratic state attorneys general backed the defendants: California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Maine, Maryland, Massachusetts, Minnesota, Nevada, New Jersey, New Mexico, New York, North Carolina, Oregon, Rhode Island, Vermont, Virginia and Washington. None have filed motions to intervene.

The Republican attorneys general of Idaho and Wyoming declined to participate in the lawsuit. Republican Ohio Attorney General Dave Yost filed a brief on "behalf of neither party," arguing in favor of the court resolving the central question raised by Texas but opposing the relief sought by the Lone Star State."

HONOR ROLL - THESE LEGISLATORS WENT AGAINST THEIR STATE IN SUPPORTING THE TEXAS SCOTUS LAWSUIT:   Georgia and Pennsylvania Legislators  https://www.bizpacreview.com/2020/12/11/gop-led-legislatures-in-ga-and-pa-file-amicus-briefs-in-support-of-texas-case-against-their-own-states-1004527/

A Majority of House Republicans  Supported

And Here Are the RINOs That Did Not Support, some going as far as to actively speak out against -        https://www.washingtonexaminer.com/news/only-70-house-republicans-did-not-sign-on-texas-failed-election-challenge

       "70 House Republicans did not support the Texas SCOTUS Election Lawsuit Every member of Republican House Leadership except the party's House Conference Chairwoman Liz Cheney answered the call.  Other prominent House Republicans who kept their names out of the brief included Illinois Rep. Adam Kinzinger and Kentucky Rep. Thomas Massie. Prominent Trump defenders California Rep. Devin Nunes and Arizona Rep. Paul Gosar also did not sign.  Republicans who either lost their primaries or decided to retire, including Texas Rep. Will Hurd and Virginia Rep. Denver Riggleman, refrained from signing the brief.

Texas Rep. Chip Roy, in explaining why he did not join, wrote on Twitter that he believed Texas's case itself was a "dangerous violation of federalism & sets a precedent to have one state asking federal courts to police the voting procedures of other states.

"I cannot support an effort that will almost certainly fail on grounds of standing and is inconsistent with my beliefs about protecting Texas sovereignty from the meddling of other states," he wrote. Outgoing Tennessee Sen. Lamar Alexander on Friday told NBC that the arguments the cases' supporters made don't "sound like a very Republican argument to me. Texas is a big state, but I don't know exactly why it has a right to tell four other states how to run their elections," he said. "So, I'm having a hard time figuring out the basis for that lawsuit." Nebraska Sen. Ben Sasse on Thursday told the Washington Examiner that he expected the court to brush the case away.
