Personally, I find myself disagreeing with both sides too much for this to be effective at all.
I'm not going to say one should or shouldn't vote Democrat. But, there are too many considerations on which I'm unwilling to compromise to just vote for the enemy of my enemy. Neither party is your friend.
Politicians will always do whatever is in the interests of the people or companies giving them votes or donations, so unfortunately without voting for the enemy of your enemy (and maybe convincing others to do so), you don't have any other tool to punish these politicians.
And they need to be punished, just like a good spanking at the right time does wonders for spoiled brats.
"unfortunately without voting for the enemy of your enemy (and maybe convincing others to do so), you don't have any other tool to punish these politicians."
From experience (see the NRA in particular), a largish single issue voting block that is willing to support either party can be enormously effective at advancing their issue.
