Example: Mitt Romney got more votes in Wisconsin in 2012 than Trump got in 2016 - and Romney LOST the state.
The House and Senate are more complicated elections.
However, since America imports 3,000 LEGAL immigrants EVERY DAY, and since 80% of those folks will vote Democrat when they become citizens, it is only a question of time before we permanently lose Congress, too.
We have Ted Kennedy to thank for this mess, that bastard. He was the one who wrote the immigration bill in 1965 that basically opened the borders. Prior to that year we only admitted 300,000 a year. We need to go back to that system.
