On this day 16 years ago, the Republican controlled House of Representatives voted charges of impeachment against President Bill Clinton!
Two charges, perjury and obstruction of justice, gained a party line majority vote, and the 42 nd President faced trial in January and February 1999, and was found not guilty, with only 45 votes for conviction on perjury, and 50 votes for conviction on obstruction of justice, with 67 votes needed to convict and remove. Ten and five Republicans supported Clinton on the two counts, and all Democrats supported the President, while 45 and 50 Republicans voted to convict.
The impeachment and trial was a mockery, with no just cause, just an attempt to besmirch the reputation of Bill Clinton, but it failed, in the sense that Clinton came out shining, growing in popularity, and this has continued since 1999.
So any attempt to impeach Barack Obama will have the same effect, with the same result, but that does not mean that the Republicans, with 54 Senators now, instead of 55, will avoid moving toward impeachment, since the GOP is much more right wing now than even in 1998-1999!
