But his long tenure isn't deterring challengers from taking aim at Dreier, who they describe as a career politician more in tune to the demands of special interest groups than the needs of his constituents.
Dreier has done little to stem the flow of jobs out of California, said Democratic challenger Russ Warner. Further, Dreier voted in favor of the privatization of social security and against Wall Street reforms that would have provided a safe guard for investors, Warner said.
"After 30 years you would think he would be doing what is right," Warner said. "It is obviously he stands with Wall Street, and I definitely stand with Main Street."
Independent candidate David Miller said he left the Republican party in 1999 because Republican officials were no more effective at stopping the growth of government than their Democratic counterparts. A general contractor and real estate developer based in Glendora, Miller said his business has been crippled by the recent economic recession.
Dreier and his colleagues in the federal government have failed to react to the crisis appropriately, he said, spending at alarming rates rather than working to reduce $1.3 trillion deficit.
"This guy claims to be a conservative every two years when he needs to get reelected," Miller said. "But he goes to D.C. and buys into the mind set there…He is the one who has been there for 30 years making this mess."
Especially egregious, Miller said, is the raiding of social security monies to pay for other costs, which he compared to a Bernie Madoff ponzi scheme. If elected he would propose mandated reduction in the deficit, he said.
The United States was founded on libertarian principles of individual freedom, free markets, private property and limited government, Libertarian challenger Randall Weissbuch said, but has become bogged down with superfluous bureaucratic departments.
