MXing money and politics. . .

Makers of the MX missile have their sights set on this fall's congressional race. The targets: members of Congress who'll have the final say on whether the controversial missile will be built and where it will be based. According to Common Cause, political action committees representing 12 of the 13 largest MX contractors will more than double their 1980 contributions to lawmakers this year - spending an estimated $780,000. The bulk of the money is going to incumbents on Capitol Hill. It's been touch and go for the MX, but so far Congress has agreed to build the first few missiles. Its ultimate success depends on where the Reagan administration decides to plant the missile.

Congress has given the President until Dec. 1 to decide on where to put it.
