If that's the case, and we're heading for a one party system regardless, then it won't matter who I vote for. Want to see a perfect example of that? Look at Venezuela.
No need to go as far as Venezuela. We have it right here in California. Both the state assembly and senate are strongly Democratic (possibly after this election there will be a Dem supermajority), and our current governor is a Democrat. Our next governor is virtually guaranteed to be Democrat. All political districts are heavily gerrymandered to make certain the Democrat stranglehold is maintained.
So the rest of the nation can look to California to see how quickly the Democrats can bankrupt the country. I find it hard to believe that anyone can, at this point, be undecided about the upcoming Presidential election.
