There’s a lot of attention being paid to yesterday’s landslide vote in the House to prevent a big tax increase next year. If you’re a glass-half-full optimist, you will be celebrating the good news for taxpayers. If you’re a glass-half-empty pessimist, you will be angry because the bill also contains provisions to increase the burden of government spending as well as some utterly corrupt tax loopholes added to the legislation so politicians could get campaign cash from special interest groups.

If you want some unambiguously good news, however, ignore the tax deal and celebrate the fact that Senator Harry Reid had to give up his attempt to enact a pork-filled, $1 trillion-plus spending bill. This “omnibus appropriation” not only had an enormous price tag, it also contained about 6,500 earmarks. As I explained in the New York Post yesterday, earmarks are “special provisions inserted on behalf of lobbyists to benefit special interests. The lobbyists get big fees, the interest groups get handouts and the politicians get rewarded with contributions from both. It’s a win-win-win for everyone — except the taxpayers who finance this carousel of corruption.”

This sleazy process traditionally has enjoyed bipartisan support, and many Republican senators initially were planning to support the legislation notwithstanding the voter revolt last month. But the insiders in Washington underestimated voter anger at bloated and wasteful government. Thanks to talk radio, the Internet (including sites like this one), and a handful of honest lawmakers, Reid’s corrupt legislation suddenly became toxic.

The resulting protests convinced GOPers — even the big spenders from the Appropriations Committee — that they could no longer play the old game of swapping earmarks for campaign cash. This is a remarkable development and a huge victory for the Tea Party movement.

Here’s part of the Washington Post report on this cheerful development:

Senate Democrats on Thursday abandoned their efforts to approve a comprehensive funding bill for the federal government after Republicans rebelled against its $1.2 trillion cost and the inclusion of nearly 7,000 line-item projects for individual lawmakers.

…Instead, a slimmed-down resolution that would fund the government mostly at current levels will come before the Senate, and Reid and Minority Leader Mitch McConnell (R-Ky.) said it will pass by Saturday.

…The majority leader’s surrender on the spending bill marked a final rebuke for this Congress to the old-school system of funding the government, in which the barons of the Appropriations Committee decided which states would receive tens of millions of dollars each year.

…Almost every Senate Republican had some favor in the bill, but as voter angst about runaway deficits grew before the midterm elections, Republicans turned against the earmark practice.

This is a very positive development heading into next year, but it is not a permanent victory. Some Republicans are true believers in the cause of limited government, but there are still plenty of corrupt big spenders as well as some Bush-style “compassionate conservatives” who think buying votes with other people’s money somehow makes one a caring person.

In other words, fiscal conservatives, libertarians, and Tea Partiers have won an important battle, but this is just one skirmish in a long war. If we want to save America from becoming another Greece, we better make sure that we redouble our efforts next year. Eternal vigilance is the price of liberty.
