1. Show me a poll that actually surveyed a majority of the Republican party or was done by pewresearch with a sample larger than their usual spread of a few thousand and, otherwise that claim (like all other poll claims) is probably BS; I myself refuse to answer any surveyor that calls my home, and I guarantee more Americans think like me in that regard than not.
2. A riot is not a coup, so Jan. 6 can't qualify. Just think for a second; they were a bunch of frenzied mobsters. There was no organized succession plan for a new government, no ability to stabilize control over the nation, no ability to even physically take control of a single part of Congress' workspace. No one, and I mean no one, could possibly "plan" such an action, because even the dumbest of people would realize that terrorizing a few congressional representatives isn't enough to take over such a dispersed democracy as the U.S.A. A truly effective coup would have to take over not only the Federal government, but also a majority of state and local governments. That is improbable to the extreme.
3. Show me text from one of the laws, just one (you can find them on the website of each state government, it's quite easy) that restricts voting and/or lowers court thresholds to a degree higher/lower (respectively) than all states currently under Democrat control. You'll have to compare all 50 state Codes Annotated to do so, but it's the only way to actually back up a claim like the one you're making (that egregious voting changes are going through). As far as state electors go, there have historically been few, if any, [I can't remember off the top of my head, but don't think it's been more than a handful] False Electors [Electors who've voted against the state popular vote] anyways. Changing these laws isn't going to change the votes of the Electors.
