Focus like a laser on the legislature, Rush Limbaugh constructively recommended on his show yesterday (subscriber only link here):

you’re going to have to focus on here to keep the country from moving left is to focus on House and Senate races, support as many Republican conservatives in both the House and Senate in your state as you can and try to limit the so-called vast increases the Democrats are expecting in this presidential election. Look, our nominee is who he is. If he gets elected, he loves walking across the aisle dealing with Democrats on a number of different things, they’re going to be the majority. Presidents like to get things done, defined as walking across the aisle and doing legislation that both parties think is hunky-dory. It is what it is. The only way it can be limited is if there are enough conservative Republicans in the House and Senate to prevent voting majorities from bill after bill after bill.
