Regarding the trend of Dogecoin after the US election, there is no exact prediction model that can ensure its price changes, because the cryptocurrency market is affected by many factors, including market sentiment, capital flow, technological development, macroeconomic and policy environment. However, based on the search results, we can understand the following:

1. **Market volatility**: Before the election, the market may be volatile, because investors' uncertainty about the results may lead to cautious investment behavior. Uncertainty about the election results may increase market volatility in the short term.

2. **The impact of specific candidates**: There is a view that if Trump wins, cryptocurrencies may usher in an explosion, because the support of people such as Musk may have an impact on market sentiment. But this prediction is not based on a strict economic model, but more on speculation about market sentiment.

3. **Polling data**: According to FiveThirtyEight, Harris is slightly ahead of Trump with 48.5% support to 46.1%. Polling data can provide some indicators of public sentiment, but they are not always accurate prediction tools, and there have been cases of polling errors in history.

4. **Capital flows**: Capital flows are an important factor affecting cryptocurrency prices. If a large amount of money flows into a certain currency, it may drive its price up. At present, some institutional investors may be adjusting their portfolios based on expectations for the election.

5. **Macroeconomic and policy environment**: The results of the election may affect future economic policies and regulatory environments, which may have long-term effects on the cryptocurrency market. For example, cryptocurrency-friendly policies may attract more investors to the market.

In summary, there are many uncertainties in the trend of Dogecoin after the US election. Investors should pay close attention to market dynamics and consider their own risk tolerance. At the same time, they should also pay attention to the high volatility and risks of the cryptocurrency market and make rational investment choices.
