Meanwhile, the Republican National Committee said yesterday it’ll spend up to $10 million on advertising in about ten states to improve its image among Hispanic voters. Party officials said the TV, radio and print ads would begin this spring and stress the values they believe Republicans and many Hispanics share. Hispanics are the fastest-growing population and they lean Democratic. In the last two presidential elections, Hispanics voted overwhelmingly for President Clinton, 72 percent to 21 percent in 1996.
