I read somewhere that the reason Republicans didn’t support him was because he pushed them to the right and they didn’t like it. I didn’t save the link because I didn’t think that I’d need it.
I think I know what you are referring to, as in the moderates/RINOS forced him out.
Not really. One reason for his lack of support was this:
"The Republican leader has taken much of the blame for the party's unexpectedly lacklustre performance in the elections, the worst performance in 34 years by a party not in control of the White House."
Also, many House members were dissatisfied with Gingrich abandoning the emphasis on cutting taxes.
Many contemporaries of Gingrich, including those who worked for him, remember that he was arrogant and not a very likeable person
