"these people seem to be a bunch of morons.."
Interesting phrasing there. Why do they "seem to be" as opposed to "are"?
Personally, I find that morons, idiots, and imbeciles are not restricted to any particluar political persuasion, rather they become affiliated with a political movement from exposure to a persuasive person with a desire to convince them. Given that morons, idiots, and imbeciles by definition are not very bright, they may not need much convincing.
"who want lower taxes and lower spending"
That is not quite an accurate statement of the Tea Party goals. But from it,I assume that you are in favor of higher taxes and higher spending. If so, do you have an example of a country that has higher taxes and spending that you would consider a good role model? I'm not going to suggest that you move there, just fix that country in your mind and ask yourself what would be necessary to do the same sort of thing in the US.
Does your model country have better social services?
If so, what are the requirements for receiving them?
Does your model country spend a significantly lower percentage of their GDP on their military?
If so, are they dependent upon another nation for any portion of their own defense?
Does your model country have a democratically elected government?
If so, how many political parties and how do candidates get on the ballot?
And one other question:
Assuming no changes to your model country, would you want to live there?
If not, why do you want to change the US to be more like that country?
If so, why change the US - shouldn't there be room for diversity among nations?.
And no, the Tea Party is not the same as the GOP. What the Tea party is, is a "good government" movement. Whether it will last long enough to be effective in attaining its goals is yet to be determined.
