ARLINGTON, Virginia (Reuters) - Newt Gingrich ended his run for U.S. president on Wednesday after dazzling in televised debates but slumping to defeat in dozens of Republican primaries under attack from rivals who portrayed him as the consummate Washington insider.
The former U.S. House of Representatives speaker, the face of the Republican Party in the mid-1990s, badly trailed front-runner Mitt Romney in polls and his campaign piled up a debt of $4.3 million.
