The Whigs were a major party. They elected 4 presidents (Harrison, Tyler, Taylor, & Fillmore). They won the presidency in 1948, and got 44% of the popular vote in 1952.
The Republican party held its first convention and nominated its first presidential candidate in 1956. The won the presidency just 4 years later in 1860.
The Whig party didn’t even nominate a candidate in 1860. In 12 short years they had gone from a major party winning the presidency to non-existence, and replaced by the GOP.
The idea that the GOP can’t be replaced is incorrect. It will be difficult, but it can be done.
We have to try; there are no political solutions coming out of the GOP. The poll watching was a disastrous failure even by their standards. What I’m calling it is “amputation”. Cutting them off is extreme and it will be painful but in the long run we’ll be better off. There can be no delay.
