Early in the campaign, Streussand did polling to ID hot topics for regular primary voters. Since that poll, I have received targetted mailings for "pro life", "tax reform" and "2nd Amendment" issues. That way he can focus mailings where they will be warmly received. I'm not sure if they are focusing on individual voters or larger areas but they are certainly tailoring the campaign to hit what's important to voters. (Not a bad thing as long as the legislative position matches the campaign position.) You are right. The voter ID techiques can go either by area or by individual. Frankly, these guys have enough money, they'll send it to everyone unless they know they are wrong for that issue. IOW, if being prolife polls 80+% in the GOP primary electorate (if not higher), just send it to everyone. Maybe skip a few areas if it polls differently there.
Flyers cost about 50 cents a pop. about 30,000 potential voters in CD-10. Streusand and McCaul put over $500,000 in this race. Each. Do the math. You could be getting a flyer every day and they'd still have money for radio and TV. (30 flyers each!)
This is a very good reason to look beyond their flyers and ask a simple question, what is their PROVEN record on conservative issues? Both Streusand and McCaul are dropping a lot of money into the race, and their campiagn consultants will tell them to tell people what they want to hear. So of course you get the flyer that says great stuff to you. You have to dig a bit deeper to see if there's meat on the bun.
Political track records are important but welcoming new candidates into the system is too. If government experience were a huge factor, you would have voted for Ann Richards instead of George W. Bush for Governor.
I haven't made up my mind yet. I may wait until Election Day to make up my mind in this race. Actually, I'm pretty happy to have several real conservative choices for once instead of just RINOs. You can't imagine what it's like living in Austin when it comes to elections. The City Council races are typically duels between the left, the far left and the space-aliens-kidnapped-my-mother left.
