About 1/3 are Conservative Republicans and another 1/3 are Liberal Democrats. The remaining 1/3 is some combination of RINOs and DINOs. When control of the house changes it is the party who loses its 'INOs that loses control. Fools in the defeated party always want to next time run members of the base. When they do that, they stay in the minority.
There are about 17 or 18 battle ground states. There are about an equal number of liberals and conservatives in a battle ground state. The election outcome is deterimined by the swing voters. Swing voters are not ideological. They sometimes vote for conservatives and sometimes vote for liberals. But they mostly vote for their own kind. That is non ideological 'INOs
Good to see ya out and about, Common Tator. :-)
Nice cute, clean, mathematically symmetrical theory. Pundits love it. Alas, there is no evidence it's true.
Elections are decided by who gets off their butts and votes and who stays home. No one changes their minds. Sorry to spread heresy among your easy theories.
