because they are hypocrites.....conservatives have zero credibility on the topic of fiscal responsibility...ron paul the original tea-bagger....only got 6% of the GOP primary vote during the summer of 2008.
70% of our current deficit is the result of GWB's spending...and most of that money was squandered in Iraq...chasing down hussein's imaginary WMD's.
teabarggers is a jeanine garofalo/msnbc term... so i will ignore that... and the tea party movement didn't start until the 2nd term of the bush presidency... for the reason that people didn't know any better... it took word of mouth for it to spread... ron paul helped a lot... a lot of the things he says would make sense in the home, with living within your means and not racking up excessive debt. the media chose not to cover any of this real conservative talk until after obama got into office... it has existed... the media chose to make bush look like a jackass (which he was, to an extent) so they could get their guy into office... they like stirring up things... always making everything look bad so the sheep think everything is an "outrage".
the true conservatives were "whining" as you say before obama took office... just that no one was listening because it didn't sound as sexy to the media that mostly leans to the democrat side.
