Last time I checked, on Tuesday night it had 59.3 million voters. Give or take you and your buddies.
My ballot in Texas had a straight ticket option for something known as the "Republican Party," something known as the "Democratic Party," something known as the "Libertarian Party" and a couple other write ins. There was nothing on it called the "Party of Lincoln" though, thus it is physically impossible that any Texan could have voted for your mythical "Party of Lincoln." I suspect the same is true of every other state, and given the usual petition barriers to creating a new third party, I doubt that your "Party of Lincoln" appeared on any ballot anywhere save your own write in.
Hold on. I just checked the domain names and it turns out that there is indeed a Party of Lincoln - www.partyoflincoln.org. It's hosted on geocities and features a sillouette of a guy in a stovepipe hat as its logo. The rest of the site hasn't been developed though - probably an indicator that their only member is also their webmaster. Hey, wait a minute...is that your personal website, non-seq?
All my choices were Republicans. There were no Party of Lincoln candidates on my ballot.
