Sen. John McCain (R., Ariz.) at last unveiled plans for new tax cuts Tuesday. His campaign surrogates announced over the weekend that tax-cut plans were coming, but in his "new" stump speech Monday, McCain made no mention of any cuts, leaving the media to wonder who was in charge of the campaign.

The proposals released early this morning outline new tax cuts to help seniors, investors and workers receiving unemployment benefits. McCain argues his new plan would attract investors to capital markets, unlike Sen. Barack Obama (D., Ill.), who has proposed rules easing tax restrictions on 401(k) withdrawals.

McCain said in a campaign appearance Tuesday:
"It is essential that we avoid an exodus of capital from the market. Senator Obama yesterday offered up a proposal that would have the effect of encouraging early withdrawal of funds from 401(k) accounts, by suspending penalties through 2009. This is an invitation to capital flight, and therefore to continued instability in the market, at a moment when exactly the opposite is needed."
Last week he said he would change rules that force seniors to liquidate 401(k)s at age 70.5 and allow them to stay invested.

McCain's new plans would go further, reducing the capital gains tax for 2009 and 2010 to 7.5% from its current 15%. He would also cut the capital gains taxes from redemptions on 401(k)s to 10%. Furthermore, he would increase the tax deduction on losses from long-term capital gains vs. ordinary income from its current $3,000 to $15,000 for the years 2008 and 2009.

But would McCain's plans actually attract capital to the market? His plan for seniors would definitely preserve some capital in the market for a short period. However, his plans to lower capital gains taxes (on regular investments and 401(k)s) and increase the tax losses might have unintended consequences. Those portions of his plan could encourage investors to make one-time sales to capture lower capital gains and increased tax write-offs. Such equities sales would facilitate capital flight.

Obama did announce a plan yesterday to allow withdrawal from 401(k)s, although the amount would be limited to $10,000. It remains unclear how many people would utilize the plan. Certainly, it would prompt some to reduce their retirement savings, moving money from capital markets into the everyday economy to pay for expenses and liabilities.

What would attract investors to the market would be a permanent reduction in the capital gains tax, not a short-term reduction. It also would make sense to increase the capital loss vs. ordinary income to offer investors greater flexibility to manage their portfolios.

In McCain's newest stump speech -- at least today's version -- he reiterated his plans to buy mortgages to help those who are facing foreclosure. His plan for the most part helps those with assets -- real estate and stocks. But he won't stop there. He also targeted those receiving unemployment benefits by suspending the federal taxes on unemployment for 2008 and 2009. The McCain campaign noted this would help 3.6 million unemployed workers.

One thing has become clear in recent days. Both McCain and Obama appear willing to offer new plans to stave off an economic crisis. However, neither of the candidates have said how they would pay for them. Worse, both campaigns have dodged the issue of fiscal sanity in the presidential debates and the VP debate by glossing over it with open-ended promises to make spending cuts.

The new economic plans -- and the massive tab to taxpayers -- should make for an exciting final debate on Wednesday night between the two candidates.
