In preparation for the big dollar presidential campaign spending of television ads, Democrats have picked up the pace of online ads on Google and Facebook, reversing what was a 2-1 spending edge by President Donald Trump as recently as March, Axios reported Sunday.

Since the start of 2019, Democrats have spent a combined $12.7 on those ads, while the Trump campaign as spent $7.9 million, according to the report.

Now, that does include a field of about two dozen Democrats and just one U.S. president, but former Vice President Joe Biden just officially announced his candidacy last month and has recently surpassed President Trump in online advertising, according to Bully Pulpit Interactive.

Since unveiling his Democratic primary intentions, Biden has outspent President Trump $1.5 million to $969K – $960.8K to $623.2K on Facebook and $541.6K to $346.6K on Google. South Bend, Indiana Mayor Peter Buttigieg ($387.9K) has also outspent President Trump on Google.

According to Axios, the early campaign spending online helps optimize campaigns and coordinate where the big dollars go later in the 2020 presidential campaigns. They do so by taking individual donations, collect campaign data, and build up lists.

The spending by Democrats does not mirror currently polling numbers, according to RealClearPolitics polling averages.

The top five in the polls:

1. Biden.
2. Sen. Bernie Sanders, I-Vt.
3. Sen. Elizabeth Warren, D-Mass.
4. Sen. Kamala Harris, D-Calif.
5. Buttigieg.

The top five Democrats in online ad spending since April 20, per Bully Pulpit:

2. Harris.
3. Buttigieg.
4. Warren.
5. Entrepreneur Andrew Yang of New York.

Sen. Sanders is seventh among Democrats in online ad spend, also surpassed by Gov. Jay Inslee, D-Wash.
