Trump can start a new party an instantly put the GOP out of business. Something that’s been needed a long time.
That, of course, assumes President Trump and Republicans fail to succeed in courts, the Electoral College, and the U.S. House. The vast majority of Americans still have little or no clue that President Trump is contesting the election. Almost everyone just assumes that "President-Elect" Biden will be inaugurated on January 20. The Democrat Party Cabal's (DPC) fake-news MSM & Big Tech/social media companies almost totally dominate the webosphere, network news, local news, major newspapers, etc. Just like the vast majority of citizens in Communist China, the vast majority of citizens in the United States have almost no clue what's going on with the election, "special thanks" to the DPC's fake-news MSM & Big Tech/social media companies' intense 24/7 censorship.
All of this is to say that if President Trump started his own MAGA Party, it would certainly attract a lot of Republican voters. However, initially, because of the fake-news MSM & Big Tech/social media companies' constant censorship, a lot of Republicans (who falsely think there's little or no election fraud) will remain in the Republican Party because they think Biden "won fair and square." So my wild guess is that, initially, maybe 1/3 to 1/2 of Republican voters would join Trump in his MAGA Party. That would virtually guarantee Democrats win the majority of elections moving forward. But as Democrats win more elections (and enact more of their Marxist Communist policies), there eventually will be a huge outflow of Republicans from the Republican Party to a MAGA Party. At that point in the future, there will also be disaffected, anti-Marxist Independent & Democrat voters also joining the MAGA Party, too.
You don't get it, if the Dems steal the Presidency, they will steal the Senate.
They will then pack SCOUTS, and eliminate the filibuster.
This will result in a ban on fossil fuels, private firearms ownership, free speech, and open borders.
Universal Medicare will be forced upon us, and only palliative care will be made available to those suffering from cancer or over 75 unless they are well connected.
This is not conjecture or hyperbole, the Dem leadership have openly proclaimed this over the last decade.
The United States will exist in name only.
