Don't like Republicans so vote Democrat?

A funny thought occurred to me as I lay awake trying to sleep. A lot of people are very mad (justly so in my opinion) at the Republicans for the way they ruled over the last eight years.

So in consequence they are voting Democrat now.

But this just does not make any sense. We have Republicans acting like Democrats, and you hate them for it, so you vote Democrat?
How were Republicans like Democrats? Let us enumerate:

Reckless foreign wars? Republicans, yes. Democrats, yes.　(You dems don't forget Somolia, Sudan, Yugoslavia, Haiti, Aｆgｈanistan, Iraq all attacked or invaded during President Clinton's terms.And of course the real big one, Vietnam, was a dem fiasco.

Sexual scandals? Repubs yes. Dems, yes. (Barney Frank's Home Porno Emporium and Brothel, anyone?)

Political corruption? Repubs, yes. Dems, ha ha ha ha ha. Far too many to number.

Huge spending? Repubs yes, in spades. Dems, let us whisper just one name, Obama.
