Stocks fluctuated on Friday, Dec. 1, as Senate Republicans made progress in getting their tax bill over the finish line. 

The Dow Jones Industrial Average was flat, the S&P 500 rose slightly, and the Nasdaq dropped 8 points. 

The chances of the bill's passage looked more certain after prominent holdouts Sens. Steve Daines, Ron Johnson and John McCain voiced support for the legislation. Daines and Johnson became a "yes" after Senate leaders agreed to increase the deduction available for pass-through income. The deduction amount was raised to 23% from 17.4%, according to analysis by The Wall Street Journal. 

A day earlier, McCain said he would support the legislation on Thursday. In a statement, McCain said that the bill "though far from perfect, would enhance American competitiveness, boost the economy, and provide long overdue tax relief for middle class families." However, a number of economists have criticized the bill's logic -- tax relief for corporations does not necessarily inspire increased reinvestment and higher worker wages. In fact, the New York Times reported that an initiative to deliver corporate tax savings in 2004 was funneled toward share buybacks, instead.

Senate Republicans have delayed further votes on their version of a tax bill until late Friday morning after running into a procedural roadblock. Late Thursday, Nov. 30, a Senate rule-making office turned down a so-called trigger mechanism that would have raised taxes if the bill's revenue goals were missed, Bloomberg reported. Three Republican senators, whose votes are crucial for passage of the bill, had insisted on the trigger.

The bill's passage is not yet certain with a a few holdouts still concerned over how cuts will drive up the deficit -- Republicans can only afford to lose two votes from their own party. The Joint Committee on Taxation said the bill will add $1 trillion to the deficit over a decade, and that economic growth from the tax cut will only offset $407 billion of the $1.5 trillion cost over the next decade.

Markets rocketed to records on Thursday on high hopes Republicans can deliver on their promised corporate tax cuts. The Dow reached a new record for its third day in a row, while the S&P 500 beat a record set on Tuesday, Nov. 28. The bill provides modest tax breaks for the middle class and significant benefits for the wealthy and corporations and will require borrowing some $1.5 trillion to add to the federal deficit.
