Re: “the Tea Party basically the old conservative wing of the Republican Party...”
You don’t know what your talking about.
The TEA Party is made up of folks of all political persuasions.
Yes, there are some old conservative Republicans, but there are also Democrats, Independents, Libertarians, unaligned voters — but mostly a bunch of just pissed-off Americans.
In the 2010 election, perhaps, but now? The conservative wing of the Republican party...easily over 75%. That constitutes “mainly”. And you’re welcome.
