To get the discount with Uber: launch the Uber app (make sure you've updated to the most recent version), tap Menu > Payment > Add Promo Code and enter the promotional code VOTE2018. This will allow you to request your ride using their special in-app polling place locater, though for the deal to be valid you'll have to select the most affordable tier option available in your city (e.g., Express Pool, Pool, or UberX, in that order). Just a heads up that you'll only be able to get $10 off your ride to the polls.
Lyft is handing out promo codes for 50% off your ride to your voting location on Tuesday. To get your code, you'll need to visit this page, and then plug it into your app by tapping the Promos tab. It's also important to note that the 50% off deal is only good on your ride to your polling place (and applies to a standard ride up to $5). Lyft is also taking things a bit further by providing free rides to underserved communities through nonpartisan nonprofit partners like Voto Latino, local Urban League affiliates, the National Federation of the Blind, Faith in Action, League of Women Voters, and the Student Vets of America.
